spp1ic=moniueaintranet,1913.` serialuavsaesa T all whom it may concern Be it known `that I, CAsIMln DE Pnosz'rN- SKI, subject of the Emperor of Russia, residing at London, England, have invented certain new and useful Improvements in -Kinematograph Cameras and Projecting flcation.

Apparatus, of which the following is a speci- Thisinvention relates cameras and projection apparatus of the kind in which a broad film isI used, the pic.

tures on the ilm being arranged in transverse parallel rows, and the film being reciprocated horizontally as well as being intermittently fed forward longitudinally.

The object of the present invention is to provide an improved apparatus of this-type which is simplified in construction, eflicient in operation and which enables the film to be readily inserted in position and removed after exposure. s

In the accompanying drawings Figures 1 and 2, are respect1vely a sectional elevation and a sectional plan of one form of apparatus according to the invention, the sections being taken respectively on the lines I-I, II-II. Fig. 3, is a detail sectional elevation on the line III-III Fig. l, looking in the direction of the arrows. Figs. 4 and 5, are detail cross sections of modifications in the form of gutter in which the lm is collected after exposure. Fig. 6, is a sectional plan showing in detail the -adj ustable spring 'plates for the exposure gate. Figs. 7 and 8, are elevations of the spring plates. Fig. 9 shows a portion of film with the pictures arranged in transverse parallel rows.

I will now `describe in detail the form of' apparatus illustrated inthe dra-wings and will then describe the operation thereof. a, is a broad film having two sets of Rerforatidns b, and 0,-the perforations c, 'being elongated as known to allowforshrinkage of the film.

d, is a supporting spindle on-WhichtheA roll of film freely unwound therefrom. The spindle d',

is hinged so that it can be swung to one side to fac1litate the insertion and removal of the film into and from the apparatus. For-this purposey the spindle d, has a bent en d; e, extendinginto 'a lug f, You the partition 9 which forms art of the framework of the apparatus.. lphe end c'of the Spindleld, is

- to receive 'a 'spring hall--I to kinematograpl;y

, a, 1s shpped, sc that it canbe catch It, which lholds it'in its normal or .closed position, the spring pressed ball catch k, being mounted in the framework. From they spindle d, the film a, ispassed over a guide roller Z, freely mounted on. hinged` s ndle m, one end n of which is mounted on ugs o, on the partition g, and provided withV a head p, so that the guide .roller Z, can be swung to one side to' facilitate the insertion oftheVv film. The end ofthe kspindle m, is recessed to receive a round head r, of a pin which is impelled toward `the e'nd g,by a spring s. The guide roller Z, can thus be swung tozone side or back again into its normal position and will be automatically engaged and held in that position by the round'headl r. The lilm a, is -next passed over sprocket pinions t, having teeth rought into engagementv with 'the 'erforations t, and o, of the lilm, the sproc et inions It', being mounted on a tubular shart a,

' so that they are free-to slideaxially thereon,

but are compelledv 'to rotate therewith as Patented oet. 6,1914.

part z', of the hereinafter explaindd. -Groov'ed rollers fv,

mounted on a spindle fw, press the film a, lightly onto the pinions i there being one roller 'v opposite each pinion t, although only one is showny inv Fig. 2, the other and art of the spindle fui, being omitted in order t at the hinge 3 for the door 2, may beshown clearly. The' grooved rollers o, are free to rotatev and also to slide on the spindle lw,

which is carried by levers a', pivoted to a hinged door 2. One of the levers im has a'pin y, engaged by a spring z, which is also mounted on'the hinged door 2 and presses the rollers lvyinto engagement with the lm. VThe door 2 is hingedv at`3 to the partition g, and it forms part of the so called exposure gate, the other artcomprising the stationary lens plate et.

he hin edf door 2 has an opening 5 oppositev to tie exposure window 6 in the lens plate 4. rIhe window G is in turn opposite to the lens 7 which is conveniently carried in a tube 8, provided with a rack 9 adapted to'beengaged by a pinion 1O earr1ed by a ixed tube 11,` in whichthe tube 8 telescopes. The pinionlO is adapted to be rotated by the spindlef121, by means of a slotted head 13 4act'zessible from outside the casing, so as vto enable the lens` to b e focused. A spring' tongue 1-2 engages with the lens tube 8 and engages the end 32 of the door 2. The lens late 4 and the hinged door 2 are respectively tted with-spring plates 14 and 19 intended to grip the film between them lightly when the hinged door 2 is in its closed position. The function of the plate 14 is to alter the position of the actual window opening relatively to the lens; the plate 19 presses the film against the plate 14.

In order to protect the lm, strips of velvet or other flexible material 18 and 23 are mounted on the lens plate 4 and hinged gate 2 and also on the spring plate 14 and 1 9. (One piece of velvet is fastened to the plate 19 and to the gate 2. The other piece coversthe plate 14, `but can move freely on the gate 4. rl`he spring plate 14 has spring tongues 16, which pass through slots 17 in the lens plat/el 4 andbear against the same so as to hold the plate 14 in any position in which it may be adjusted. Similarly the spring plate 19, has tongues 21 which pass through slots 22 in the hinged door 2. The plate 14 has an aperture 15 which is smaller than the apertures 20 and 5 and window 6. By sliding the plate 14 on the lens plate 4 and door 2, the position of the actual exposure opening can befvaried slightly and therefore the position'of the actual exposure opening in relation to the lens can be carefully set. After the film has passed through the exposure gate it is allowed to .freely enter a gutter 24, which may Vbe conveniently mounted upon the lens plate 4, directly below the exposure gate. The gntteris preferably `of the curved form shown so that as it receives` the loose end of the film it will allow the same to freely roll up into a' coil as indicated at 26, the film rolling up automatically under its elasticity. To protect the lm against scratching, the gutter 24 is provided with a velvet strip 25, which will maintain the'iilm out of contact with the gutter 24. lf desired, and in order to permitof daylight unloading of an exposed film, a' box 27 maybe inserted in the gutter 24 the box 27 being provided with a slot 28 arranged directly below the exposure gate so as vto receive the -iilm a. lnorder to prevent ingress of-light whenthe apparatus 1s open, the box m-ay be provided with velvet or flexible strips 29 around the slot 28. The gutter may be round, square or of any other form in cross section.

In a modification as indicated atFig; 4, a single centrally mounted cylinder or roller 30may be arranged longitudinally in the passing between the roller 30, and gutter 24 and wrapping itself around the roller which will act as a guide and tend-to assist in the automatic rolling of the film. In a further` formas indicated .in Fig. 5,- the gutter 24, is provided with antijA 1action rollers 31 't6 guide the lm as it first .eters the gutter and to aid it in its shutter.

winding action. The mechanism so far described only treats with the guiding of the lm in its longitudinal movement and its exposure. rihe piuions t, before referred to, are intermittently rotated to eect the desired longitudinal feeding movementI of the ilm a, and they are intermittently moved Without rotation in an axialdirection on the tubular shaft u, to effect a step by step lateral movement of the film @,in order to expose the film picture by picture at the window 6 the pictures so obtained being arranged in lateral rows.

l will now describe the means by which the intermittent rotation of the pinions t, is effected and also the means by which the intermittent axial movement of the pinions is obtained. The pinions t, are connected together by a rack 34 which is provided with alternate right and left hand teeth. rlhe rack 34,' is a free lit in a slot 35 in a tubular shaft u, and prevents the pinions t, rotating relatively to the shaft u, although they are free to moveA axially thereon. The tubular shaft u., passes throughthe partition g, and is fitted with a toothed wheel 36 which is adapted to be engaged by a spring pawl 37 carried by a lever 38 pivoted on' a, pin 39.

The lever 38 is held in its normal or upper.

u, and the pinions t, thereon, in order to elfect the'required longitudinal feed of the film a.. The cam 41 =is mounted on a sleeve 42, which in turn is l'mounted on a shaft 43 andcaused to rotate therewithv by a pin 44 carried by the shaft43 and entering the slot 45 of the sleeve 42. Theshaft 43 is rotated by means of the handle 44', which is mounted on av shaft 45', which drives the shaft 43 through the medium of toothed wheels 46, 47,V 48 and 49. VThe toothed wheel'48f-lis also utilized to drivethe shutter 50, through the medium of wheels 51 and 52 the latter of which is mountedY on the spindle 53 of the The shutter rotates within a protective casing 54. The cam 41 is only adapted' to be brought over the lever 38- when it is required to depress the same, namely when the required longitudinal feeding movement of the film is to take place, and this axial inovement of the cam 41, is effected by a slottedl cam 51, which is mounted onthe shaft 45. y.The slotted cam 51, receives a pin 52 carried by an arm 53y of a bell crank lever pivoted at 54 the arm 53 engaging with a vcollar 55 on the sleeve 42. f The slottedcam the t, is to .be effected.

:,nasee v 34, and therefore, the pinions t, are to be moved from right to left the pawl 57, engages with the corresponding teeth of Athe rack 34 whereas' when the rack 34 is to be moved from left to right the pawl 58 en` vgages-.with the corresponding teeth of the yrack, the change being effected by a partial rotation of the pawl rod 56which brings one pawl into engagement with the rack, and the .other pawl out of engagement therewith. The end59, of the pawl rod 56 is free whereas the pawl rod 56 nearer itsy other end is held in suitable bearings at-the position 60, 6l sothat when 'the pawl rod 56 is reciprocated it will slip over the teeth' on its return movement, as is common with rack and pawl mechanism.A The pawl 57 is' shown in the drawings in engagement with the rack- 34 the pawl. 58 being shown out of engagement therewith, it being assumed/that the rack 34 has just completed its lateral step byl step movement from the right to the left. The rotation of the pawl rod 56 to change the positions of thepawls 57 and 58 is effected. by the forked` arm 62, of they bell 'crank lever, which is pivoted at 54 and the other'ar-ln 53, of which, as before described has a pin 52'in operative engagement with" the slotted cam 51. The forked arm 62 engages with a collar 63 freely mounted on the tubular shaft-u.- 'lhe interior or bore of the collar 63,is provided with a longitudinal slot which receivesa cranked part 64, of the pawl rod 56. A pin 65 Fig. l, passes through the collar 63 and entersia'helical slot 66 in a tubular shaft u. When the slotted cam 51 moves the` arm 53 of the bell crankv lever it also movesv the arm 62 thereof and the latter .causes the collar 63 to slide jalong the tubular shaft u. When this takes place the pin' 65 is caused to follow the helical slot in the tubular shaft u, so that a slight helical movement is imparted to the collar l 63, andthe collar through the mediumof thecranked part 64 of the rod 56 imparts the required 4rotary movement tothe pawl, rod 56 to move the pawls 57, 58 into their new positions. The reciprocation of' the pawl rod 56-is effected by means of a lever. 67 y ivoted at 68 to a stationary bracket 69..`

rlhe lever 67 is forkedv to form two abutments 70, 71 which are adapted to be en?` gaged by either of two cams 72 and 73 mounted on the shaft 43. The cams 72 and 73,` are angularly displaced by the amount ofv 180 i-n relation to one another and they are also displaced longitudinally upon the shaft y43 so Ithat only one at a time can operate upon the level` 67. Wheneither of the cams 72 or 73 is in operative position it fits between the two abutments and 71 of the lver 67, and during each rotation it presses first on one abutment and then on the other abutment so that it moves the lever first in one direction and then back in the reverse direc-- `tion. One cam is used for reciprocating the pawl rod 56 when the pawl 57 is in engagement, and the othercam is in operative engagement when the other pawl is engaging with the rack. In Fig. il, the cam 73, is shown engaging with the lever 67. The lever 67 has an upper end 74 which enters the slot 75 in the sleeve 76 mounted upon the pawl rod- 56. The end 74 of the lever 67 is adapted to engagewith the end 77 of the rod 56, when the lever 67 moves to the right. The end 74 engages with a screw 78 when the lever 67 moves to the left, the screw 78 being screwed into the end of the sleeve 76 so that its relation to the end 74 of the lever 67 can be varied. In order to permit adjustment of the screw 78 fro-m without the casing 7 9 of the apparatus the screw is provided with a squared extension 80 which is free to slide through a bush having a milled head 81, rotation o-f which will cause rotation of the screw and, therefore, an adjustment of its end relatively to the end 74 of the lever 67. .By this means the clearance between the end of the screw 78 and the end 74 of the lever 67 can be 'increased or decreased so as to inoreaseor decrease the .lost motion between the lever 67, andthe pawl rod 56. v

Assuming the end 77 .of the pawl rod 56 to be adjusted or set once for all relatively to the sleeve 76, then the lever 67 will always move the pawl rod 56 to a determined posivtion to the right, but accordingly as the clearance between the end 77. and the end 74 Y 'of the pawl rod. This adjustment permits' of ithe regulation which kmay be necessary, should. it be found that lowing to slight irregularitiesbetween the'pawls and rack,

A'the end picture of one'row does not register with the first picture of the preceding row.

The shifting of the cams 72 and 73 into 'and' out of engagement with thev lever 67 is effected by the sliding of the sleeve 42 through the-medium of the slotted cam 51 and lever arm 53. It .will/be understood that when the cam 41 is over the lever 38. neither of lthecams 72, 73 is in operative 'engagement with the lever-67 and that when either of said cams is in operative engagement with said lever the cam 41 is to one side or the other of the lever 38.

Assuming theiparts to be in the position shown in `the drawings, except that the hinged gate 2, is in its closed position shown in Fig. 3, and not'its open position shown in Fig. 2, the apparatus is put in motion by the rota-tionl of the handle 44'.- The first thing to occur will he -the movement of the lever arm 53 by the slotted cam 5l, and con- Vthrough the medium of the cranked part 64, v,

engaged by a spring 83.

and will impart a rotary movement thereto. The movement of the lever arm 53 will also cause the sleeve 42 to slide on a shaft 43 the arms 53. acting upon the collar 55. This .will bring the cam 4l-over the lever 38 and asl the shaft 43 is rotated, the cam 41 will depress the lever 38 which through the medium of the spring pawl 37 and toothed wheel 36 will rotate the tubular shaft Ji. This rotation will impart the necessary longitudinal feed to the lm a, so as to bring another lateral strip of Elm down into the exposure gate ready to receive a lateral row or series of pictures thereon.l The continued sliding of the sleeve 42 will eventufally move the cam41 away from the lever 38, and will 'bring the cam 72 opposite to the lever 67. The continued rotation of the handle 44 will cause the shaft 43 to rotate and the cam 72 will oscillate the lever 67,.'

and therefore, its end 74 will continue to reciprocate the pawl rod 56. rflue p'awl 58,

which is in engagement with the rack 34l will during this reciprocation of the rod 56 impart the necessary step by step movement to the rack 34 and therefore, to the pinions t, so that the nlm a, will be carried step by step. from left to right to expose the fresh lateral strip of nlm step by step at the .win-

dow 6. When the pawl 58 has engaged with the last tooth and has carried the rack 34 to its extreme position to the right the slotted cam 51 will lagain oscillate the lever arms 53, and 62 so that the collar 63 will be moved back aga-in along the tubular "shaft u,

to rotate the pawl rod 56 so asfto disengage the pawl 58 and rengage the pawl 57 with the rack 34. Moreover, the lever-farm` 53 will slide the sleeve A'42 back on the shaft 43 so as to move the cam 7 2 out of engage'- ment with the lever 67 and move the cam Y '4l into engagement with the lever 38, which will -be depressed to again rotate the pinions t, to feed down the film again-longitudinally the required means for another lateral strip.

The continued*movementv of the 'handle 44 .will then cause the cam 4l to be disengaged with the lever 38, and the cam 72 to he` brought inltol engagement with the lever 67 so that the rod 56 is once more reciprocated to cause the pawl 57 to Work the rack 34 step by step from right to left, and these operations will he repeated until the .whole of the film a, has been passed through the exposure gate. y

It will be understood that the film is gripped with sufiicient friction between the rollers fu, and pinions t, and.' also between the spring plates of the exposure gate to hold it in position and prevent it moving while the pawl is slipping back over the teeth of the rack at any time; moreover, in order to prevent any accidental movement -of the pinionst, a brake disk 82 is mounted on the tubular shaft u, and is adapted to be Y l claim l.
